Customizing Keyword Blocking URL Checking
You can use commands to set how much of a website’s URL the content filter is to check for
keyword blocking. See the appendices for information on how to access and use the command
interpreter.
14.6.1
Domain Name or IP Address URL Checking
By default, the NBG334W checks the URL’s domain name or IP address when performing
keyword blocking.
This means that the NBG334W checks the characters that come before the first slash in the
URL.
For example, with the URL
www.zyxel.com.tw/news/pressroom.php
, content filtering only
searches for keywords within
www.zyxel.com.tw
.
14.6.2
Full Path URL Checking
Full path URL checking has the NBG334W check the characters that come before the last
slash in the URL.
For example, with the URL
www.zyxel.com.tw/news/pressroom.php
, full path URL checking
searches for keywords within
www.zyxel.com.tw/news/
.
Use the
ip urlfilter customize actionFlags 6 [disable | enable]
command to extend (or not extend) the keyword blocking search to include the URL's full
path.
14.6.3
File Name URL Checking
Filename URL checking has the NBG334W check all of the characters in the URL.
For example, filename URL checking searches for keywords within the URL
www.zyxel.com.tw/news/pressroom.php
.
Use the
ip urlfilter customize actionFlags 8 [disable | enable]
command to extend (or not extend) the keyword blocking search to include the URL's
complete filename.

Static Route Screens
This chapter shows you how to configure static routes for your NBG334W.
15.1
Static Route Overview
Each remote node specifies only the network to which the gateway is directly connected, and
the NBG334W has no knowledge of the networks beyond. For instance, the NBG334W knows
about network
N2
in the following figure through remote node router
R1
. However, the
NBG334W is unable to route a packet to network
N3
because it doesn't know that there is a
route through the same remote node router
R1
(via gateway router
R2
). The static routes are
for you to tell the NBG334W about the networks beyond the remote nodes.
